I'm just wondering if anyone can offer any advice on how best to go about creating a 2-D game with zooming/scaling features akin to the early Samurai Showdown games. In this case it would be a side scroller a la Metal Slug, the zooming would come in as more enemy sprites entered the screen, or when facing a large sized boss. A feature that would be both cosmetic as well as functional to the game.

I've done some reading and noticed a few suggestions that included drawing different sized sprites, a standard size and zoomed out size.

Any thoughts?

Thanks for your time.
